[Buildroot] [git commit] package/v4l2grab: update version to fix build

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=a5ec50b2cc874a2e8a711792d673f0c51b5142b2
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

v4l2grab uses clock_gettime which is provided by -lrt, so we must check
and link with it.

Also, silence autoreconf when outside a git tree.

Fixes:
